Abstract

An improved wood burning stove for providing heated air to a room or similar area includes an enclosed fire chamber, a hearth at the bottom of the fire chamber, draft inlet means at the front of the fire chamber and a flue at the rear of the fire chamber. Within the fire chamber is an enclosed air chamber having lower and upper portions; the lower portion communicates at the bottom of the stove with the ambient air and extends upwardly adjacent the rear wall of the fire chamber to a point below the flue, where it joins with the upper portion. The upper portion of the air chamber extends upwardly toward the front of the fire chamber at an acute angle with the horizontal, preferably between five and twenty-five degrees; at the forward end of the upper portion the air chamber communicates with one or more air pipes which extend to the front of the stove and there open to the ambient air. Ambient air is heated by passing it through the air chamber and air pipes after they have been heated by hot gases rising from a fire burning on the hearth; the hot gases contact the air pipes and the bottom surface of the air chamber's upper portion and, because their normal path of travel to the flu…
